6 Claims.

This invention relates to new and useful improvements in water closet flushing apparatus and has as its principal object the provision of means whereby closet bowls can be flushed with a small amount of water under low pressure.

Another important object of the invention is to provide a low pressure flushing apparatus which will afiord an economic substitute for the more costly high pressure types of installations now found in general use.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

' In the drawings Figure 1 is a side elevational View of the apparatus.

Figure 2 is a sectional view taken substantially on the line 22 of Figure 1.

Figure 3 is an enlarged vertical sectional view taken substantially on the line 3-3 of Figure 2.

Figure 4 is an enlarged fragmentary vertical sectional view taken substantially on the line 4-4 of Figure l.

Figure 5 is a fragmentary vertical sectional view through the perforated tube of the water container. 7

Figure 6 is an enlarged cross sectional view taken substantially on the line 66 of Figure 3;

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes a water closet bowl having a flushing conduit 6 leading thereto and in which is a control valve I.

A reducing T-fitting 8 connects the conduit 6 with the flushing apparatus, the upper end of the T 8 being connected by a nipple 9 with a reducing sleeve II) at the lower end of an elongated cylindrical water chamber II which has brackets I2 thereon whereby the same can be attached to a wall or other support. The upper end of the container II is closed by a screw cap I3.

A pipe section M extends into the lower end of the fitting 8 and from this pipe section I4 extends an elongated tube I5 which extends upwardly to a point near the cap I3 and then bent backwardly to extend downwardly and terminate adjacent the lower portion of the container II.

, As can be seen in Figure 3, this tube I5 is perforated at regular spaced intervals from a point just above the lower end of container I I, to its extremity.

The lower end of the pipe section I4 connects to a T-fitting l6 which, in turn, is connected by a pipe section I! to a header l8, the latter forming a head for a barrel I9. A second header 2D is provided at'the lower end of the barrel I9 thus defining an injector chamber 2|.

A short pipe section 22- extends into the lower portion of the header 2t and from this pipe section 22 extends an injector tube 23 which extends upwardly into the barrel I9 and terminates adjacent the upper end thereof.

The lower end of the section 22 connects to a T-fitting 24 to which is connected a supply cutolf valve 26. A pipe section 21 extends downwardly from the fitting 24 to connect to a T- fitting 28 from which extends an air chamber 29, this being in the form of an outwardly extending pipe section connected to an elbow, and, in turn, connected to the elbow is a vertically extending barrel a.

As shown in Figures 2 and 4, an upper chamber 3! is provided and extends from the T-fitting I6, the same consisting of a laterally disposed pipe connected by an elbow to a vertically extending barrel b.

Extending below the fitting 28 is a pipe section 32 which has a drain cock 33 extending laterally therefrom. A cap 36 closes the lower end of pipe section 32.

The function of air chambers 29 and SI is to prevent water hammer and the resultant noise when valves are opened and closed causing sudden flow and stoppage of water, and to act as reservoirs for water under pressure of compressed air in the top of chambers'29 and 3|, this water forming a quick supply for pipe [5 whenvalve I is opened. These chambers 29 and 3| with their reservoirs of water in addition to preventing air hammer tend to keep up the pressure in barrel I I because they furnish water which does not have to come thr'ough supply pipe 30. Upper chamber II being filled with air when the apparatus is assembled with valve 26 closed and valve 1 open, when valve 1 is closed and valve 23 open, water from the supply line through pipe l5 enters chamber II and compresses the air already in that chamber in the. top thereof.

When valve I is open water under pressure of compressed air in barrel is forced through pipe 6 to flush the toilet and at the same time water from ejector 23 is forced into perforated tube I5 and flows rapidly out of the tube I5 into barrel II through the perforations immediately above the water level in barrel II. The water from tube I 5 always flows into barrel II from immediately above the water level in that barrel, this preventing any loss of pressure in barrel I I for two reasons, one being that the water does not have to go to the top of barrel II, with the iesultant loss of pressure due to the weight of he water column, in tube l5, and secondly, since the water is not introduced into the bottom of barrel H or below the water surface the water in barrel H going to the toilet is allowed to flow down Without interference from entering water in tube I5. By these actions and the function of tubes (1-29 and 17-31, pressure is maintained in barrel II and water rushes out of it through valve 1 with great force.

When valve 1 closes itself, it being a spring valve which closes as soon as sufficient water has passed through it to flush the toilet, and handle is released, the pressure and supply is again quickly built up in barrel 1 I, and in barrels a-28 and b3l and the apparatus is ready for another operation almost immediately.

The function of barrel i9 is to form a partial check to water entering tube IS, in this way preventing interference with the entry of water a from barrel b -3| which is much more quickly available than water from supply pipe 36.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope'of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. In a device of the class described, a vertically arranged combined air and water chamber, an outlet conduit connected with the lower end of the chamber, a supply pipe and a gooseneck pipe connected with the supply pipe and extending upwardly into the chamber with the bight of the gooseneck located adjacent the top of the chamber, that part of the gooseneck pipe located Within the chamber having perforations therein for permitting water to flow from the gooseneck pipe into the chamber above the water level in the chamber, whereby the incoming water will not interfere with the water flowing from the chamber.
